Physical properties of fluororubber O-rings: fluororubber is a copolymer of vinyl fluoride and hexafluoropropylene. Due to the difference in molecular structure and fluorine content, the chemical resistance and high temperature resistance of fluororubber O-rings , Low temperature resistance type is also different.
The English name of fluorine rubber is FKM, and the fluorine rubber material produced by DuPont is named viton or VT for short. Volding chooses Japan's Daikin and American DuPont for the rubber material of fluorine rubber. Because of the good choice of rubber material, the quality of Volding's O-ring seals has always been stable and has been recognized by customers.
The comprehensive performance of fluorine rubber is very good, whether it is oil resistance, high temperature resistance, wear resistance, and corrosion resistance. The commonly used colors of fluorine rubber O-rings are brown and black. There is also green, and other colors can also be made.
Elastomer: fluororubber bisphenol or peroxide vulcanized fluororubber O-ring has strong high temperature resistance and low temperature resistance (-40-240ºC) performance, good oil resistance, very good resistance to media, especially for Freon, Good resistance to acids and alkalis Resistant to all carbohydrates (oils, greases, solvents) Fluorine rubber has low gas permeability and high resistance to chemicals in air pressure It has very strong resistance to compression set and tear resistance Strength, wear resistance and high temperature resistance VITON
Application of O-ring: It is often used in the sealing of automobiles and aircraft engines. It can be used for a long time at 250 ° C. It is very suitable for the sealing of the engine power output shaft. It can also be used for engine valve stem seals, cylinder liner seals, clutch seals, and air filters. Fluorine rubber seals are the only ones that can be used under high vacuum conditions.
